[V4,1/2] ath10k: Move ath10k_vdev_stop() up before ath10k_vdev_start_restart()

Commit Message

Vasanthakumar Thiagarajan March 2, 2015, 11:27 a.m. UTC

This patches does not modify any functionality. Just a code move
so that ath10k_vdev_stop() can be used in ath10k_vdev_start_restart()
for any failure cases which involves vdev_stop().

V2:
     - Call ath10k_vdev_stop() when ath10k_monitor_recalc() failed.
       This results in code move done in patch 1.

V3:
     - Make change specific to AP mode and update the commit log.

V4:
     - Rename the helper which is used to check is promisc mode is
       to be disbled.
     - Add warn when ath10k_monitor_recalc() and ath10k_vdev_stop()
       fails.
